I have a brand new in the box Muzzy Dual Exhaust System, with the Carbon Fiber Mufflers as pictured herein on my 2010 C-14.
Had the entire piping system coated in baked on flat black ceramic coating both inside and outside the pipes...the coating provides.....cooler running pipes, a little quieter, better air flow ( faster) escaping of the gases, picks up about 2 HP, and looks great when mounted.
The inside pores of the pipes are filled so the gases are able to escape and vent a bit quicker......it is an expensive process..but adds to the asthetic appearance of the bike. You have to roll on the throttle in the upper rpm ranges to experience the way this Muzzy Sytem puills....it is expensive....but the best always costs a little bit more.....
Pipes..............................................................................................$1600.00
Coating..............................................................................................300.00
My time, shipping, transportation, scheduling for the coating work........$100.00
Turn key exhaust system................................................................$2,000.00
Buyer pays shipping...................................................................about $45.00
